CURRYCOMB.

Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed May 19, 1916. Serial No. 98,687.

To all whom it may concern:

Be it known that I, IIENRY LARSON DUX- STAD, a citizen of the United States, and a resident of the city of Cambridge, in the county of Dane and State of Wisconsin, have invented a certain new and useful Improvement in Currycombs; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms a full, clear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to improvements in curry combs, and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described and then pointed out in the claims.

The object of this invention is the production of a comparatively simple, cheap and very efficient self cleaning curry comb.

Referring now to the drawings already mentioned, and forming part of this specification, Figure 1 is a. plan of my improved curry comb. Fig. 2 is an end elevation of my device. Fig. 3 is alike section on line 33 ,of Fig. 1. Fig. 4 is a similar section on line H of Fig. 1. Fig. 5 is a plan of one of the units detached. Figs. 6 andv7, are a plan and a section, respectively, of a slight modification. Fig. 8 is a perspective view of a fragment of one of the duplicate units.

A, in these drawings denotes my curry comb as a whole, and 10 indicates one of a series of duplicate units comprising the same. This unit consists of a serrated, vertical, currying blade 11; a parallel, substantially vertical, though slightly diverging, smooth-edged scraper blade 12, and a plurality of connecting members 13. The scraper blade 12 is slightly shorter in height than the currying blade 11, to permit of the proper functioning of the serrations 141. Projecting from the upper edge of the currying blade 11, toward the scraper blade 12, are a plurality of horizontal lips 15, having perforations 16, for suitable rivets 17 EX- tending upwardly from the scraper blade 12, medially of the length thereof, between the lips 15, is a projection 18, terminating in a horizontal lip 19, having perforations 20, for rivets 21.

Connecting the lips 15, of the several units along their marginal edges, by the rivets 17 aforesaid, are sheet metallic strips 22, and

medially of the length of the units 10, the lips 15 are connected, by the rivets 17, to bars 23, terminating in a suitable handle member 24. It will thus be observed that the whole comb A, comprised of the units 10, with the lips of the currying blades 11, firmly riveted to the strips 22, and the handle bars 23, forms a particularly rigid structure, and one not liable to distortion under heavy and hard usage. The scraper blades 12, being only connected to the connectlng members 13, and not to the strips 22 or 23, render these blades susceptible to depression, due to the resiliency of the connectlon 13.

The lips 19 of the scraper blades 12 are connected together by the rivets 21, to a metallic strip 25; and upon this strip is placed an upwardly bent strip 26, to form a truss connection with the strip 25, and also to afi ord a striking member against which the comb may be struck when it is desired to clean the carrying teeth. The strips 25 and 26 being connected only to the scraper blades, it is obvious that when the strip 26 is struck against an object, such as the wall of a horse stall or the like, the impact will effect the depression of the scraper blades, causing them to scrape along the adjacent currying blades, beyond the serrations therein; and that the natural resiliency of the connections 18, will effect the return of the scraper blades to their normal position.

In assembling the parts or units, the scraper blades are caused to contact the currying blades with their lower edges, while the upper edges are slightly divergent therefrom. This is done to eliminate the possibility of the blades becoming rusted together due to the moisture and acids common to an animal barn or stable.

In Figs. 6 and 7, I indicate means for fastening the bars 22 to the units 10, without the use of rivets. In practising this modification, I punch oblong slots 16, in the lips 15, instead of the rivet holes 16. In the bars 22, I pierce and bend up, ears 17, which ears are passed through the slots 16, and bent over into close contact with the under side of the lips 15. This construction is cheaper than rivets, and produces substantially the same results. In many cases I may provide only one course of rivets 21, instead of two courses, as shown in Fig. 1.

I have heretofore described this invention with considerable minuteness, as to details of construction, but I desire it to be under stood that many of these details of construction may be changed by a person skilled in the art to which my said invention appertains without departing from the scope of the same as defined in the following claims.

Having thus fully described my invention I claim as new, and desire to secure to myself by Letters Patent of the United States:

1. A curry comb, including a plurality of duplicate units, each of said units comprising a currying blade, a scraping blade, said scraping blade being integrally formed with said currying blade, means connecting said currying blades, and means connecting said scraper blades.

2. A curry comb, including a plurality. of duplicate units, each of said units having a currying blade, and integrally formed therewith a scraper blade, said, scraper blade contacting with a currying blade of an adjacent unit, means connecting said currying blades, and other means connecting said scraper blades.

3. -A curry comb, including a plurality of duplicate units, each of said units having a.

currying blade, and integrally formed therewith a scraper blade, said scraper blade contacting with a currying blade of. an adjacent unit, means connecting said currying blades, other means connecting said scraper blades, and means for depressing said scraper blades.

4. A curry comb, including, a plurality of duplicate units, each of said units having a currying blade and a scraper blade, resilient members connecting the blades ofv individual units, means connecting the currying blades of said units, and other means independently connecting the scraper blades of said units.

5. A curry comb, including a plurality of duplicate units, each of said units having a currying blade and a scraper blade, resilient members connecting the blades of individual units, means connecting the currying blades of said units, other means independently connecting the scraper blades of said units, and means for depressing said scraper blades.

6. A curry comb, including a plurality of duplicate units, each of said unitsv being formed from a single, sheet m etallic strip and having. a currying, blade and a scraper blade, said blades being connected by a yielding connection, means connecting said currying blades of the several units, and other means independently, connecting said scraper blades of said units.

7 A curry comb, including a plurality of duplicate units, each unit having a currying hand.
